Hello All,
I am new to the Jensen Healey world and have a few questions,
1) do the seats adjust and how do you remove them?
2) does anyone advise floor pans to be riveted if only replacing a section or do you recommend replacing the entire floor pan?
I will have more questions as the project goes along so please bear with me.
Thanks,
Mike

The seats have a fore/aft adjustment as well as a backrest tilt adjustment. To remove them, there are four nearly inaccessible screws under the seats that fasten the seat frame to captive nuts in the floor mounts. Because of the rubber mats that were original equipment, the floors and mounts are very susceptible to top down rusting. Once you get the seats removed and the floor coverings out of the car, you can appraise the the damage and needed repairs if any. If you have not removed the rubber mats, you may be in for a shock (Ask me how I know).

There are many ways to replace flooring, but of course the best is to use new steel and weld since this will be the strongest possible repair. Replacing only the corroded portions is very acceptable, and certainly easiest. You will probably find that the seat mounts will also need replacing (as I did) since they seem to go just about as fast as the floor itself.

As to methods that are accessible to the home mechanic, panel adhesive, riveting, and brazing are options all with various advantages and tradeoffs.

My total restoration has been a 2-1/2 year journey to date, but I am almost there. New floors, paint, new interior, new fuel system, rebuilt suspension, bumpers, etc have all been done. What's left? Soft top and engine which is currently at the machine shop.

Welcome aboard!

Vance

Thanks, the seats and rails have been replaced, but they rock like there are parts missing, I have the original seats. I'll get the seats out then access. Where is the adjustment, I might just not know where to look?

Hopefully this won't take too long as it is in pretty good shape except for a few things.

The rocking may be due to corroded seat mounts which are sheet metal with captive nuts and welded to the floor pans (arrowed in the picture). As far as accessing the adjustment controls, if the seats are not original all bets are off. 

The fore/aft adjustment on an original seat is a lever below the outside edge of the front seat bolster, move the tip of lever towards the door and slide the seat. The tilt for the back is a lever on the side of the seat closest to the door, at the junction between the bottom of the seat and the seat back.

If you are having difficulty finding the adjustments, I must ask if the new seats have any adjustments at all.

I have not found any adjustment on the new seats, I think they came from a GT, I did find the adjustments on the original seats. I will try looking again tomorrow.
Thanks for the help

Mike,

"Hopefully this won't take too long", that's funny.

I'm not clear on what you've got going here. So you want to remove the seats to access the floor pans and cross members (seat mounts). You have two sets of seats, the originals still in the car and a set from a Jensen GT correct? The GT seats are the same ones used in the Jensen-Healey so all adjustments are the same. The only real difference between the two is upholstery and headrests.

The chrome lever on the door side of the seat bottom moves the seatback fore and aft. The lever under the front of the seat moves side to side and moves the seat forward or back in the car.

"The seats and rails have been replaced", what seats were replaced, the originals? If that's the case wouldn't you already know how to remove the seats? And what rails, do you mean the crossmembers that the seats are mounted to or are you talking about the adjustment rails on the bottom of the seats?

Once the seats are out you can assess the floorboards and crossmembers, Delta has all pieces you'll need.

noomg,

By not taking long depends on what else I find but overall, the car is in good shape.
I just purchased the car a couple months ago and the seats were changed out before I got it. I have looked all over and NOT found any chrome handles on either seat, I did find them on the original seats. After further review I don't know if the cross-member rails were replaced, the ones on the seat were, since they are still attached.

I have called delta several times with no response.

Any more suggestions I'm all ears.

I have a mess!! The reason I could adjust the seat was because it was all F^(ked up. It was not even secure, that's why it wobbled and wouldn't move. There are NO cross rails, and the bottom has been bent to make it fit, I will try to include some pics. At this point I thinking of starting over, thoughts?
Can't figure out how to load the pics, I've changing the size, any suggestions.
